[noRSA] Bootloaders for E8, Patched CG31 for E8

[Skrilax_CZ]

Which one you tried? Was it a tested one (06.A3, 06.A5 and 06.AC) (assuming you flashed mathcing noRSA version for your bootloader)?

[Av3LaR]

As far as i know, once RSD say, Please manually disconnect your device is completely safe to unplug your phone and then turn it on, either way is OK, and i've done it both ways, and well nothing has happened to my phones.

I post this thread on moto.it168.com

and someone tested failure

his E8's BL and FW is 06.a3(stock) and 10.13r(stock) at beginning

he flashed BL 06.a3(stock) -success

then flash 02.07 FW(stock)
show:MEM_MAP Blank
Service Req'd.

after that he try to flash BL 06.ac(stock) and BL 06.ac(noRSA) -success
and show:Err：XX，XX，XX，XX，XX

then flash 02.07 FW(stock) Again
show:Err：A5,70,27,00,1F

then flashed ilove3d’s FW
show:Err：A5,70,27,00,1F

even flashed back to 10.13r(stock) the phone cant boot
and show Err：A4,70，00，00，1F

final flashed 14.XX(stock) and boot success

What's the problem?

[Av3LaR]

What noRSA did he flashed, tell him to flash a stock FW, and tell us what happen

[NestorM]

he's saying tested, 06.A3, 06.A5 and 06.AC are the only ones tested.

I've edited my reply that post before
it's more clear now

Nice, now i see, first, WOW, then, tell him to recharge his phone, how? with another E8, as his won't charge, there's no system right now, and well now, i'd go for flashing with 06.A3 stock, and then a stock FW, any FW [as long as it's not a sticky nor 06.A9 one is fine] and seeing if it boots normally if so, we're done, if not well, perhaps Nestor has some ideas, diferent to the ones i gave you.

@Nestor
If you understood the post, then why you didn't give an answer?

This is my understanding and personal experience with bootloaders on moto phones. Motorola makes it such that if the hardware is the same then bootloader UPGRADE is possible but never a downgrade. Seing as how your friend had 06A3 stock, then he flashed a firmware and got MEM MAP BLANK. This happens when you flash a CG31 from a firmware that is NOT made for your bootloader as CG31 contains memory mappings.

If he flashed a full MP it probably had CG34 as well. This is another bootloader stage and is known for killing phones permanently as it happened to a friends ZN5 (different LJ version same concept, doesnt matter).

Then you say he upgraded his Bootloader to 06AC, second mistake. Now hes stuck with that bootloader and if he tried to downgrade it will probably kill his phone beyond repair. So my best suggestion to you is to flash a stock 06AC MP. Nothing modded, just a stock MP from Motorola. If that fails then flash it again, if that still fails then flash a sticky 06AC MP as thats probably youre best shot at reviving the E8.

A) Usually you don't want your client to be able to downgrade your software, first, there is no logical reason (from your point of view), second, downgrading file is from B -> A does not match upgrading file from A -> B. That's a common design. (See games for example). So either you do complete reinstall or are just "stuck" with the new file. The only exception would be when the A and B files overwrite the same thing.

B) CG34 has nothing to do with bootloader. Yet is not to recommended to be mixed from various firmwares without examining it. The ZN5's case is because 06.2A version have different memory mappings then the 06.2B / 06.2DP version.

C) I don't see a reason why he would flash an old bootloader - it is known it kills phones and you should know it before attempting to do so. Patching CG31 will resolve the issue -> to boot up old firmware on new BL and myself I don't see a reason why you would flash old fw when there is a 06.AC version.

D) He said to flash a stock firmware if you noticed btw. Besides the discussion about flashing the 06.AC bootloader is from elsewhere.

B)Your wrong.

taken from motofan

Also, MEM MAP BLANK (from my experiences) on MagX phones reffers to an incorrect flashing of CG31

C)He flashed a newer bootloader over his older one, i dont know about E8 firmwares, i just know some work only on specific bootloaders, if he is flashing a firmware that is for 06A3 it will never work, and as far as i know no one has patched CG31 for the E8

D) Yes, he said he flashed a stock firmware, you dont know if that was compatible with his firmware. The discussion of him flashing 06AC is important here, he upgraded his bootloader! therefor he needs the correct flash files to fix his phone, and if he tries downgrading it will most likely kill his phone

B) CG34 loader loads the linux firmware itself (think Ubuntu loading screen). While the CG30 & CG32 (Irom Loader) can be reffered as basic input and output system, but thats what we call bootloader on Motorola devices. Therefore it has nothing to do with the BL it is just ignited by that.

C) True, patches must exist since there are fws for 06.A9 / 06.AC running on 06.A3. (Or the CG31 is left out of the flash.)

D) Downgrading the bootloaders is not recommended the way 06.A9 and newer to 06.A3 (06.A5) as it results a nice brick. I don't see a need for that however since there is a No RSA 06.AC version and the firmwares can be made compatible. btw. he (Av3Lar) didn't say a thing about that

[无根草]

so why it seems the BL 06.ac(noRSA) doesn't work?

[Clonza]

Maybe the problem is not in the bootloader.
The firmware must done something(modifying memory mapping?) to prevent older one to boot. Since flash the new stock firmware WITHOUT bootloader will make the same thing happen.

NoRSA 06.AC works, but the firmware you flashed was not compatible with it.

How and what should I do with the FW to make it compatible with BL noRSA_06.AC?
